Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00788 - 0.01457), b=3.09 (3.04 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.60 se; based on food items.

Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec=21).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Catégorie de prix (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 66.8 [17.7, 163.7] mg/100g; Iron = 1.5 [0.8, 3.5] mg/100g; Protein = 19.1 [17.1, 21.3] %; Omega3 = 0.824 [0.336, 2.190] g/100g; Selenium = 32.2 [13.3, 69.7] μg/100g; VitaminA = 51 [17, 144] μg/100g; Zinc = 1 [1, 1] mg/100g (wet weight);
